I am selling this because I gave up on breastfeeding. I also purchased this item used, and it originally did not come with a power cord, so I used batteries. It worked without any problems. I used it about 3 times. I was told the previous owner used it for about a week, and the condition is clean. One spare valve was included. As a bonus, I will include 4 batteries! Furthermore, I have 3 leftover breast milk freezer bags, 25ml size, so I will include them! (I will include them by default, but I can remove them if you prefer.) Please understand that this is a used item before purchasing. If you think buying a new one is a waste, but you want to try a breast pump, please consider this!
